@rolltime Last job I rolled the #OpenDyslexicFont out to all Ubuntu workstations and laptops via puppet as part of the standard build.
I've set it as my default font for Libby on Android, it makes a difference.
I use #AtkinsonHyperlegibleFont for Element on my laptop, and shareable documents (eg Résumé).
I should update https://www.figjam.nz/geekery/fonts.html to explain how to configure either as one's default font.
